caret

问题 How do I know the exact period of the caret blinking on a certain Windows system? (Programmatically using .NET) 回答1: You can P/Invoke it. http://www.pinvoke.net/default.aspx/user32.getcaretblinktime 回答2: You can always simply P/Invoke GetCaretBlinkTime (Daniel's answer gives the copy/pastable signature).

问题 I need to put together an editable text area that has a custom caret (cursor) which is different from the default blinking vertical line. Is the caret a "skinnable" property of text input? Please note that I am not asking about the mouse pointer cursor which can be set using the CursorManager.

问题 I'm making a text-editor application, and I've run into an issue with my CaretListener not being fired when text is typed or pasted after a JPopupMenu is shown. I have added the CaretListener to a JTextArea with textArea.addCaretListener(new CaretListener() { public void caretUpdate(CaretEvent e) { runThisMethod(); } }); This works fine, and calls "runThisMethod()" whenever the caret moves (key press, text selection, etc...). In my application I have a JMenuBar, and also a JPopupMenu added

问题 I am trying to reproduce in my app a UX similar to Microsoft Excel / Google Sheets when you type of formula and you have an autocomplete dropdown for the different formulas and variables you have at your disposal. For that purpose, after having validated the autocomplete, I want to be able to control the position of the cursor.
